HENRY M. scrrneivnnr., or BUFFALO, NEW vonk.

. Movniarn VEHICLE-JACK.

Specification of Letters Patent. Patented Apr. 16,1918.

Application led May S, 1917. Serial No. 167,165. l

To all whom t may concern Be it known that I, HENRY M. SGHRANKEL, a citizen of the United States, residing lat Buffalo, in the county of Erie and State of New York, have invented a new and useful Movable Vehicle-J ack, of which the following is a specification.

The main object of my invention is to provide a movable jack, which will combine simplicity of construction, durability'and quick and easy action, to adapt it for rapid use in turning or shifting vehicles in garages, show-rooms or other places where vehicles or cars are housed.

T o that end my invention consists broadly of a base or platform mounted on swiveled casters, posts rigidly mounted on opposite ends of such base or platform, means at the upper ends of the rigid posts for engaging and sustaining the axle of the vehicle and a lever-arm mounted on the base or platform midway of the rigid posts.

My invention further consists of certain details of construction all of which will be fully hereinafter described and pointed out in the claims.

Referring to the drawings:

Figure 1 is a front elevation, partly in section, of my improved movable jack.

Fig. 2 is a side elevation of the same.

Fig. 3 is a vertical section taken in the line 3 3 of Fig. 1.

Fig. 1 is a horizontal section taken in the line of 4 4 of Fig. 1. c

Fig. 5 is a perspective view of one ofthe washers employed in adjusting the height of the rigid posts.

Referring to the drawings:

1 is the base or platform mounted upon the casters, preferably four in number. These casters are swiveled to the underside of the base l, and are free to swing in any direction as the base is moved in operation.

5 5 are vertical posts with integral flaring bases 6 6 rigidly secured to the upper side of the base 1, and at opposite ends thereof. These posts 5 5 are provided with rectangular sockets 7 7 which extend to the Haring bases 6 6, supporting devices consisting of the upper curved or semi-circular members 8 8, and the rectangular shanks 9 9 are adapted for removable engagement with the rectangular sockets 7 7 of the vertical posts 5-5. To meet the requirements for varying heights of the vehicle axle l have provided the washers.l0 10 with cen tral rectangular passages 11 11l adapted for loose register with the rectangular' shanks 9 9 of the supporting devicesr,

12 is av lever-arm provided lat its' upper end with the cross handle 13. ltslower end is screw-.threadedv for engagement with the upper end of 'the curved,connectionvl the lower end of which is in screw-threaded engagement'with the vertical shank v15 of the l-base-plate 16, rigidly secured to the basel,

midway of the vertical posts 5 5. This ar-V rangement permits the swinging of the lever-arm 12, horizontally from side to side, as desired, but no movement, in a vertical direction, of the leverearm 12, upon its support 16, is possible.

In operation, the lever-arm 12 is swung upwardly, which tips the base 1 and its supporting devices 8 8 to enable these supporting devices to be placed in holding engagement with the vvehicle axle 17 (shown in dotted lines in Figs. 1 and 2). A downward movement of the lever handle will sufice to elevate the axle and with it the at tached wheels to the desired height, the washers 10-10 being employed to meet the requirements for varying heights of the vehicle axle. my improved jacks, one at the front axle and the other at the rear axle, I am enabled to turn or shift the raised vehicle in any With theemployment of two of manner desired. One jack only is employed be accomplished with an entirely rigid lever-arm.

`The advantages of my improved Jack can be summed up in a few words.

The operative parts are reduced to` a mm1- mum to save cost of construction. They are rigidly and compactly assembled and they require no adjustment, save the placing in position of the washers (or their removal) to meet requirements for varyingl heights of the vehicle axle.

Claims 1. A movable vehicle jack consisting of a base or platform mounted on swiveled casters, posts rigidly mounted on opposite ends of such base or platform, removable and adjustable means at the upper ends of the rigid posts for engaging and sustaining the aXle of a vehicle and a lever-arm mounted on the base or platform, midway of the posts.

2. A movable vehicle jack consisting of a base or platform mounted on swiveled casters, posts rigidly mounted on opposite ends of such base or platform, removable means at the upper ends of the rigid posts for engaging and sustaining the axle of a vehicle and a horizontally swinging lever-arm mounted on the base or platform, midway of the rigid posts.

3. A movable vehicle jack consisting of a base or platform mounted on swiveled casters, posts rigidly mounted on opposite ends of such baseor platform, removable and ad-V justableV means at the upper ends of the rigid posts for engaging and sustaining the axle of a vehicle and a horizontally swinging lever-arm mounted on the base or platform, midway of the rigid posts.

Signed at Buffalo, in the county of Erie and State of New York, in the presence of two subscribing witnesses, this 16th day of April, 1917.
